Abstract

본 발명은 전기밥솥의 공정 초기에 이상공정 상태를 사전에 판별하여 이상공정 상태가 고온 상태로 까지 진행되지 않도록 하여 전기밥솥의 성능향상을 도모하고자 한 이상공정 제어장치 및 제어방법에 관한 것이다.The present invention relates to an abnormal process control device and a control method for improving the performance of the electric rice cooker by determining the abnormal process state in advance at the beginning of the process of the rice cooker so that the abnormal process state does not proceed to a high temperature state.

이러한 종래기술은 공정시간 및 최대온도(온도 퓨우즈가 165℃시 단락) 설정후에 이상공정 상태를 판별하기 때문에 공정의 진행이 1차 가열공정에서 과열상태를 검출할수가 없으며, 2차 가열 공정 진행시 취사량이 경계영역인 경우에는 과열 판정 에러현상이 발생하고 과다 취사량일 경우에는 공정진행이 최대량으로 진행되므로써 전기 밥솥은 정상동작을 수행하지 못하는 문제점이 있었다.Since the prior art determines the abnormal process state after setting the process time and the maximum temperature (short-circuit when the temperature fuse is 165 ° C), the process is not able to detect the overheat state in the primary heating process, and the secondary heating process proceeds. In the case of the cooking quantity at the time of the boundary region, an overheating determination error phenomenon occurs, and in the case of the excessive cooking quantity, the electric rice cooker cannot perform the normal operation because the process proceeds to the maximum amount.

이를 개선고자 하여 본 발명은 공정초기에 타이머(TIMER) 구동에 의한 시간설정에 따른 온도차를 검출하여 소정온도(예로서 3℃) 이하 또는 소정온도(예로서 25℃) 이상일 경우 이상상태로 인식하고, 이와 같은 이상상태 발생 즉시 경보 및 표시수단을 통해 단시간 내에 사용자가 이상 상태임을 알 수 있도륵 함으로써 전기밥솥의 파열등 기기의 손상을 미연에 방지코자 한 것이다.To improve this, the present invention detects the temperature difference according to the time setting by the timer (TIMER) operation at the beginning of the process and recognizes the abnormal state when the temperature is lower than the predetermined temperature (for example, 3 ° C) or higher than the predetermined temperature (for example, 25 ° C). In order to prevent damage to the device, such as a burst of an electric rice cooker, the user can know that the user is in an abnormal state within a short time through an alarm and display means immediately.
